SNOWPLOW.

Application filed February 15, 1928. Serial No. 254,554.

This invention relates to a snow plow, the general object of theinvention being to provide means for lifting the snow by the low andthen moving the snow to either si e of the plowso that the snow is notpackedby the plow and resistance offered by the snow to the plow ispractically eliminated, this result being secured by forming the plowwith an inclined top portion up which the snow passes from a cuttingblade at the lower front end of the incline and a scraperlike bladeadjustabl mounted on the incline for deflecting t e snow moving up theincline to either side of the out being made by the plow. The adjustableblade can also be set transversely of the incline to push the snow aheadof the plow and it can also be used to cut down the walls of a drift andto remove the piled up snow at the sides of a cut previously made by theplow.

A further object of the invention is to provide means for so connectingthe plow with a tractor that the tractor will move the plow inwheelbarrow fashion, with adjustable shoes at the front end of the plowso that the weight is distributed between the shoes and the tractor,thus reducing the resistance offered by the plow to the tractor.

A further object of the invention is to provide a hydraulic liftactuated by the tractor for lifting the plow and the snow piled on thesame so that the snow can be removed from a drift to another point bybacking the tractor, this action being somewhat similar to that of asteam shovel.

Another object of the invention is to provide wings at each side of theframe of the plow adjacent the tractor for increasing the width of cut,such wings being foldable at the sides of the frame where they will bebe out of the way when not in use.

This invention also consists in certain othor features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a plan view of the plow attached to a tractor.

.In these drawings, A indicates the side members of the frame of theplow, each of which is composed of the channel bars land the plates2 sothat thesides of the frame are closed and these frames are connectedtogcther by the cross bars 3. The upper edge of the front portion ofeach side member slopes downwardly to the front end of the member and atop plate or member 4 is fastened to said edges so thatthis member 4forms an incline which lifts the snow as the plow travels along, as themember passes under the snow and causes the snow to travel This memberor incline 4 is wider at its upper end than at its front or lower end,with its side edges projecting beyond the side members A. A cuttingblade 5 adjustably fastened .to the lower or front end of the plow bythe bolts 6, the member at having rows of holes 7 therein adjacent itsedges for receiving the bolts. This blade 5 is formed with asubstantially straight flat front part 5, the front edge of which isbeveled as shown and its rear portioninclines upwardly and-rearwardly sothat it rests flatly upon the lower part of the insection on line 6-6 ofFigcline 4. A runner 7 is connected with the,

point of the part 5 of the blade, this runner acting to cause. the plowto ride over obstructions on the road surface. The lower end of themember f is recessed, as at S, to space this part of the member from theroad surface, the recess being covered by the blade. A shoe 9 isboltedto the front part of each side member for supportin the front part ofthe plow from the road surface, each runner being adjustable verticallyby iaving a plurality of holes 10 therein for receiving the bolts. 7

The rear ends ofthe side members of the plow are attached to a tractorsuch as shown at B, through means of the bars 11, each of which has anenlargement 12 its lower end which has a hole therein to receive a pivotpin 13 which projects from each side of the tractor adjacent the centerthereof and near the bottom of the ground engaging element of thetractor. hese bars slidingly fit in guideways formed by the channel barslet fastened to the rear end of each side memher A, the rear bar beingremovable for permitting the bar 11 to be placed in the guideways orremoved therefrom. A plate 15 is secured to the inner bar 14 of eachside member and forms portion of the guideway. Thus the plow issupported by the shoes and the bars 11 pivoted to the tractor inwheelbarrow fashion so that the weight is equally distributed betweenthe shoes and the tractor and the resistance offered by the plow to thetractor is reduced to a minimum. The manner of connecting the rear partof tie plow with the tractor permits vertical and swinging movement ofthe plow in relation to the tractor so that the plow can readily passover rough roads and obstructions on the road surface and the plow canbe lifted as will l e hereinafter described.

A frame 16, includin a pair of vertically arranged chain el bars 17forming guideways, is connected with the cross bars 3 under the rear endof the member 1 and this frame is braced by the upper and lower bars 18,the upper bars being connected with the under side of the member 4t andthe lower bars being connected with the cross pieces 3, with theirfrontends connected with the front ends of the upper bars. Runnerforming pieces 19 are placed at the junction of the,

two of bars these runners being arranged under the front end of themember 'l. Similar runnerforming pieces 20 are al- :21 which act asguiding means on the-frame r saddle 22 which its over the rad ator ofthe tractor. The rear ends ofthe lower bars 18 are connected by theplates 23 with the in Figure 1.

by thebars 17 and a roller 27 is carried by the lower end of this frame25,. this roller engaging the road surface. The cylinder and piston forma hydraulic lift for the plow for swinging it around a horizontal axisformed by the pivot pins 13. v

The cylinder is supplied with oil or other fluid by a pump 28 attachedto the rear part of the tractor and driven from a power takeoff thereof.The pump is connected by the pipes 29 with the cylinder of the hydraulicmeans. 7 V

A scraper-like blade 30 is adapted to be fastened to the member 4 by thebolts 31 which pass through the longitudinally extending slot 32 inl theblade, the member 4 being provided with rows of holes 7 in addition totherows '7 for receiving the bolts 31'so'that the blade 30 can beadjusted to various positions on the member e and it can also beadjusted at different angles or to a position where it will extend atright angles with the member l, as shown at dotted lines The blade canalso be moved longitudinally on the member 4 and where the position orinclination is not to be therefrom midway between thechanged, thisadjustment can be made with out removing the bolts, due to the slot 32.

A wing 32) is arranged at each side of the plow and each wing is hingedto each side frame A by having its hinge parts ena rod 35 carried by thebrackets 36 on tle outer bars 1 the side member. Thus each wing ishingedly connected witl each side member and it also has verticamovement as the hinge parts 3% have sliding movement on the rod Shoes 37are formed on the bottom of eachwing for engaging the road surface andeach wing is provided with a hook 38 at its upper end for engaging ahole 39 in the top bar 1 of the side member to hold the wing in raisedand folded position. As will be seen, when the wing is in this position,it will be protected from the snow by the overhanging side edge of themember l. Each wing is supported in open position by are pivoted to thewing and to a rod ll carried by some of the bars 1 of the side member,each rod 41 being slidably supported so that the braces can movevertically with the wing. These wings act to widen the cut made by theplow and wh n in open position, they extend at an incline rearwardl sothat the snow will be directed toward the sides of the cut by the wings.

In order to preventv snow being pushed under the plow and in frontof thetractor the brace bars 40 which by the wings, I provide a pair ofrunner-like members 42 which are supported for vertical movement at thecenters of the side members, these members 42 having their lower edgescontacting with the road surface through the action ofgravity as theplow moves over irregularities in the road ,surface so that they closethe space between the lower edges of the side members and the roadsurface and thus prevent the snow from the wings passing under the plowand in front of the tractor or piling up in front of the roller 27 ofthe hydraulic means. As shown, these members 42 straddle the plates 23and the lower rear cross bar 3 and are movable in the space between thelower bars 1 and the plates 2.

From the foregoing it will be seen that the plow lifts the snow insteadof moving it to one side or the other so that the snow is not packed andis moved with the least resistance. As the snow passes upwardly over themember 4, it engages the blade 30 which may be set to any pointintermediate the ends of the member 4 and this blade can also be set atany desired angle to move the snow to either side of the cut. By makingthe blade adjustable lengthwise of the member 4, it may be set to suitthe depth of snow being moved and it canalso be adjusted to throw thesnow to one side or the other of the out. The blade 30 can also be usedto reduce the height of the snow at both or either side of a cutpreviously made i by setting the blade as shown in Figure l,

and running the plow in the cut previously made so that the projectingpart of the blade will force the top of the snow bank at one side of thecut to one side of the plow so that the plow can make a new cutalongside of the first without operating in the full depth of the snow.The arrangement shown in Figure 1 can also be used'to CJI undercut thedeep drifts. In many instances, snow is piled diagonally across a roadso that most of the snow is on one side of the road. By adjustingtheblade 30 so that its extended part pro]ects downwardly and outwardly,the snow is undercut by the blade and conveyed to the opposite side ofthe road where there is but little snow. The snow above the undercutwill then fall from the top of the drift and thus reduce the excessamount of snow on one side and the snow will be conveyed to the otherside. This operation will be repeated until the cleared part of the roadiswide enough to travel on. The blade 30 may be laced at the top ofthemember4 and at rig t angles to the length, of said member to plowextra deep show. When the plow is so used, the snow is lifted to the topof the drift and forced by the blade to the sides of the cut, afterwhich the blade may be adjusted as in Figure 1 so that the piled up snowmade ration can be moved back by at a new cut may be made by he usedwhere the road is muddy beneath the snow.

Vhere the, drift is so deep that the blade 30 cannot move the snow-fromthe member 4-0 to the top of the drift at the side of the cut, thehydraulic means can be used to lift the plow and the snow thereon andthus break up the resistance caused by the solidity of the drift, thusmaking it possible for the tractor to push ahead and continue throughthe drift. 7 If this is impossible, the tractor can be backed after theplow with the snow thereon has been lifted and then the snow dumped fromthe plow when the plow has been moved out of the drift. This action issomewhat similar to a steam shovel.

By placing the blade 30 transversely at the lower part of the member 4,the plow can be used for pushing snow ahead of the plow. This positionofthe blade is shown in dotted lines in Figure 1.

By adjusting the cutting blade 5 to a high position on the member 4, thedepth of cut is reduced. As will be seen, either one or both of the sidewings may be used or both side wings may be moved to inoperativeposition. These wings increase the width of cut made bythe plow. Theshoes 9 are placed a proper distance behind the nose and cutting bladeso as to allow the plow to enter the hard snow crusts and thisarrangement, with the wheelbarrow action of the tractor on the plowenables the low to operate with the minimum amount 0 power and maximumamount of tractor traction.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readi? apparent.
